Sažetak
Our skin is subjected to daily aggression that threatens its equilibrium, its functions, and its visible beauty: chemical products, pollution, stress, irradiation from infrared and ultraviolet sources, and abrasion. The mechanisms that cause tissue damages are also numerous. It is now well recognized that much of the deterioration is caused by free radicals (radical oxygen species), generated by inflammatory reactions and by solar irradiation. The consequences can be visible or invisible: inflammation, burns, oedema, long-term illness, actinic damage, and premature aging. The aging of the skin manifests itself as drying out, loss of elasticity and texture, thinning, damaged barrier function, appearance of spots, modification of surface line isotropy, and wrinkles. Antioxidants are known to prevent agents called free radicals from damaging cells in the body and the skin. Free radicals are a result of normal body processes, but they can also be created by exposure to various environmental factors such as smoking or ultraviolet radiation from the sun, and can speed up the aging process. The photoprotective effects of antioxidants are significant when applied in distinct mixtures in appropriate vehicles. Topical application of such combinations may result in a sustained antioxidant capacity of the skin, possibly due to antioxidant synergisms. The ability of these ingredients to enhance skin functioning depends on how they are formulated into products that can maintain the integrity of the active ingredient, deliver it in a biologically active form to the skin, reach the target site in sufficient quantity to exert an effect, and properly release from the carrier vehicle. A real antiage product should not only try to correct the symptoms of age but to prevent their appearance, to protect the skin against these daily aggressions, to slow down the process of aging.
